Continuity mistake: Towards the end of the movie, in the scene where Anna is taking the werewolf cure to Van Helsing and the vampire bride stops her on the large fallen pillar, she falls so she is in a sitting position with the cure in her left hand. She then switches it to her right. Then in the close-up shot, the cure is still in her left hand and she switches it again.

Continuity mistake: In the final fighting scene between Dracula and Van Helsing it can be seen that Dracula has all his fingers. However, later in the scene, when he asks Van Helsing for the return of his ring, one of his fingers is missing.

Continuity mistake: When Velkan hangs on the rope and is being pulled up he looks down and the werewolf climbs up the wooden pole and you can see scratch marks on the top of the pole. Then the second time he looks down at the werewolf you can see the top of the pole is scratch free and the werewolf makes the scratch marks again. If you have a close look at these two scenes you can see it's the same scene played twice, but with a different roaring sound from the werewolf.

Continuity mistake: When Dracula is talking to Victor and he says "It must now serve my purpose." you can see hair hanging over Victor's forehead. When it cuts to Victor getting up while saying "What purpose?" the hair is gone from his forehead.

Continuity mistake: When Anna and Van Helsing embrace to kiss, the hands with which they caress each other change position and even totally swap in between cuts. In one shot Van Helsing will be touching her with his right hand, the next shot with his left hand, the next shot with no hand, etc.

Continuity mistake: In the opening shot at the Ball when Carl and Van Helsing are to "trade" Frankenstein for Anna, everybody has a reflection in the mirrors at either side of the ballroom although they are later to be revealed as Vampires and have no reflection.

Continuity mistake: In the beginning when Van Helsing kills the first bride with holy water he sits on the church steps. In the wide angle shot there is a lot more snow on the steps than in the close up shot.

Visible crew/equipment: As the camera moves in on the bull that is about to be grabbed by the vampire, if you look under the bull, you can see two men hiding behind it. You can see their legs. They are probably there to keep the bull standing still. When it cuts they are gone.

Revealing mistake: When firing the cross-bow, Van Helsing runs out of arrows, but the bow's cannister is completely full of arrows. In the same shot he simply spins once and they all disappear.

Continuity mistake: When Dracula and Van Helsing meet for the first time, Dracula's hand placement changes between shots. This happens twice, once when he is saying 'But like me, hunted by all others." During this, his hands move from his side to taking his gloves off. And again, when he says 'You are the great Van Helsing,' his hands move from his sides to being in the air.

Continuity mistake: When Anna tells the citizens to kill Van Helsing and Carl, the undertaker gasps and moves backwards behind Carl. When it cuts, the undertaker has slightly moved to the side of Carl instead.

Revealing mistake: When Dracula pulls the silver stake from his heart, you can see it is a prop from the way the point wobbles slightly.

Revealing mistake: When Dracula is walking upside down, and he yells "Let us Begin.", you can see the wire and pulley device underneath his feet, in between the sides of a pre-cut line on the top side of the bridge.

Continuity mistake: When Anna is hanging from the top of the roof, she places her feet against the wall before jumping. At that time you can see the wall is perfect without any cracks or marks. When it cuts to her leaping off you can see a huge crack going along the wall where she has her right foot.

Revealing mistake: At the end of the movie, when Dracula's children explode, the goop from their bodies doesn't match up with the splashes on the ground. You can see some of it hit the ground and disappear, and other places, it would hit, then the splash would occur a second or two later. It was all computer-generated, so it was just slightly mismatched. Hard to catch normally, but easy to see in slow-motion.

Continuity mistake: When Anna is looking for her brother who fell off the cliff, there is a closeup of her where you can see some bushes in front of her. When it cuts to a wide shot you can see there are no bushes anywhere near where she is standing.

Continuity mistake: When one of the brides push Anna and Van Helsing to the ground under the first attack, Van Helsing drops his spike weapon to the ground. The position of the weapon changes during the shots.

Continuity mistake: When Velkan changes into a werewolf in front of his sister he still has tattered remains of pants on him. When he goes to Castle Frankenstein, and enters through the roof his pants are gone. When the Velkan werewolf lands on the ground and starts to change back, his pants are back on.
